About 300 of Rashi's [[responsa]] and halakhic decisions are extant. These responsa were copied and preserved by his students. ''[[Machzor Vitry]]'' contains Rashi's responsa on prayer; this work was edited by Rabbi [[Simchah of Vitry]], whose son, Rabbi Shmuel, married Rashi's granddaughter Miriam (daughter of Yocheved). ''Siddur Rashi'', compiled by an unknown student, also contains Rashi's responsa on prayer. Other compilations include ''Sefer Hapardes'', edited by Rabbi Shemayah, Rashi's student, and ''Sefer Haoraah'', prepared by Rabbi Nathan Hamachiri.
